The flow on these is straight FIRE. Never streaks. They make the nibs SUPER flowy because they have to make the bodies a little stiffer than normal, because they sell them full. EMPTY, these are great as well. Just be sure not to use them on a f*ckin brick or some sh*t, because the nibs aren't all that durable. If you cop one of these or the empties, make sure to get an extra nib or two. The ink is these is raw as f*ck. It's the molotow coversall dripstick edition. If you read my review on that, you will see how much I fux with that ink. It is highly opaque, weather proof, and a bit of a b*tch to buff cuz it has bitumen (tar) in it. TBH, I would cop the empty and a refill bottle, cuz it's a bit more economically smart. you pay more in general, but you are actually paying less. you may pay like 2 or 3 times as much, but you get like 4 or 5 refills outta the empty mop if you buy an empty and a refill.
